should be utilized to begin the strengthening process. These
exercises should be done with no or very light weight, progressing by utilizing
the principles of Progressive Resistance Exercise (PRE).
Also, the aerobic fitness of the athlete should not be neglected; one should
begin interval training on a

stationary bike,

stair climber, or

elliptical
trainer.

As the hamstring begins to heal, and the athlete is able to perform the
exercises with decreasing pain and increasing endurance, more advanced exercises
should be performed. These include:

Chair walk (sit in a rolling desk chair and use the legs to pull the chair
forward),

When the athlete is almost ready to return to competition, more ballistic
training can begin. These activities include;

High knee running,

Light plyometircs such as bounding drills, and

Sprints with running starts and gradual stops, progressing to

Sprints with a standing start (or use of blocks).

If a qualified Athletic Trainer is available, ultrasound or electrical muscle
stimulation may be applied to facilitate the healing process. Please
remember that these are two potentially dangerous treatments when applied
improperly, and should only be used by appropriately trained professionals.
